Lateral rectus muscle (LRM) palsy due to a nuclear or fascicular sixth nerve lesion is rare as the presenting sign of multiple sclerosis (MS). It is more common to find this palsy in the company of other nearby cranial nerves deficits. Facial numbness in association with a LRM palsy or paresis may go unappreciated and therefore underreported. We report an unusual patient with a LRM palsy, facial anesthesia, ataxia and as the initial manifestation of MS. There was a demyelinating lesion in the pons seen on magnetic resonance imaging (MRI).
作为多发性硬化症（MS）的首发症状，因核性或束性第六神经病变导致的外直肌（LRM）麻痹较为罕见。在伴有其他邻近颅神经缺损的情况下，这种麻痹更为常见。与LRM麻痹或轻瘫相关的面部麻木可能未被察觉，因此报告较少。我们报告了一名不寻常的患者，其以LRM麻痹、面部麻醉、共济失调为首发表现的MS。磁共振成像（MRI）显示脑桥有脱髓鞘病变。
